BDO USA Appoints New Chief Operating Officer

CHICAGO, June 6, 2024 − BDO USA, one of the nation's leading accounting and advisory firms, today announced that Chief Operating Officer Steve Ferrara will retire from his position following a distinguished 33-year career with the firm. Assurance Principal Mark Ellenbogen will succeed Ferrara as chief operating officer, effective July 1, 2024. 

Collaborating with Steve over the last 12 years has been a privilege. Steve has made innumerable and invaluable contributions to the firm, including overseeing remarkable revenue growth of over 350% since 2012 and successfully establishing an Employee Stock Ownership Plan (ESOP) in August of last year. I am confident Mark will build on Steve’s legacy, and his leadership will propel us toward a new chapter of sustainable, people-first growth.

With over 30 years in public accounting and more than two decades at BDO USA, Ellenbogen has a deep understanding of the firm’s operations and has played pivotal roles in the growth and management of the Audit & Assurance practice, working with clients across various industries. As a BDO USA board member, Ellenbogen chaired the Governance Committee and was instrumental in establishing the ESOP, closely working alongside Ferrara, Berson, the leadership team and board during a transformational moment in the firm’s history. 

"Stepping into the COO role is both an honor and an exciting opportunity. I am proud to have been a part of the firm’s successes during the last 22 years and am ready to leverage our past achievements to reach new heights as an ESOP company,” said Ellenbogen. “I am grateful for Steve's guidance during this transition and the unwavering support of Wayne, the executive team and the board.”
